To all 'wiwi/ i t may 00m/ern Beit known that I, SYLVESTER H. HUNT, a citizen of the United States, residing at Bessemer, in the county of Gogeloic and State of Michigam have invented certain new and useful Improvements in Ore-Load- Lers, of which the following is a specification.

The present invention relates to ore loading apparatus, and one of the primary objects is to provide mechanism of this character that will' operate in a conned space and effect the deposit of ore or other inateria-l into a common mining buggy. Wihile particularly devised for this use, it will be obvious, however, that it is not limited thereto, but may be utilized in other industries Where material in bulk is to be transferred to a vehicle or carrier.

An embodiment of the invention is illus trated in the accompanying drawings, whereinz- Figure l isa longitudinal sectional view through the apparatus.

Fig. 2 is a horizontal sectional view.

Fig. 3 is across sectional view.

Fig. 4 is a detail sectional View on an enlarged scalethroiigh the diggin'g and elevating member.

Similar reference numerals designate corresponding parts in all the `figures of the drawings.

i the embodiment illustrated, a truck is employed comprising frairiie sections 13 and 111, the. sections being pivoted, as illustrated atilso as to permit their relativela'teral .swinging movement; The section 13 has a depressed front portion 1'6, andthe section 14 is of the same elevation asthe portion 156. The front section 14' i's 'carried on suitable Wheels 17,and the depressed portion 16 is also sup' o'rted ou wheels 18. The rear portion of t e truck frame ismounted on driving-Wheels 19 fixed to a. shaft 20 that is suit- V ably journaled on the truck frame.

The rear end of the truck framey is provided Witli "an upstanding tubular pivot 21 o n which is mounted a lateral svvingin carriage. This` carriage consists of a base rame 22 having an opening 23 that receives the pivot 21, the front portion of said base frame having a sliding bearing 2i on the elevated portion of the truck section 13 adjacent to the rear driving Wheels 19. Said frame fui'- thermore is provided at its front end With a pair of spaced standard plates-25 slidably mounted, as shown at 26 in Fig. 1, upon the front truck section 14. Standards 27 rise from the rear end of the base frame 22 and the upper ends of these standards are connected with the `standard plates 25 by inshaft 33 suitably supported on the carriage y in advance lof said motor. The supports and bearings Ifor this andV the `other shafting hereinafter described arefnot illustrated in orderfto avoid confusion andl to simplify the drawings. Their arrangement Will, course,he readily understood and apreciated'hy any one skilled in thisart. "he main driving shaft 33 is provided With a rear Worin 34 meshing Withl a WormA ear 35 that isied to a counter-shaft 36. T 'e said counter-shaft, as sh'ovvn in Fig, 2, may be coimectedfby clutches'f to cit-hei ofi a pair of sprocket 'wheels '38., Around 'these' sprocketwheels sprocket chains 39 that also pass about sprocket Wheels 1405 mounted onA stub 'shafts 41 journaled on the 'reafrlporytion of the carriage. The inner ends ofthe stub shafts 4 1 areV provided vvitli. beveled gears 4'2mesl`1ing with diametrically opposite portions of a horizontal beveled'gearll that is fixed to theupper end of a vertical iio i quentl shaft 44. The shaft 44 is disposed laxially of the pivot 21, andv is providedi'at: its lower end with a beveled Ofear 45-mesh'inl withva similar gear 46 on, a horizontal aft 47. The shaft 47 is provided with a worm 48 meshing with a worm gear 49 fiXedN-to'theaxle 20. With this construction, it will-be evident uthat the truck and themechanism carried by it can be moved in either direction by clutching either of the sprocket wheels 38 to the counter-shaft 36, and that the truck .will be' at a standstill if both`r of said sprocket wheels are unclutched from the counter-shaft.

The mairidrivinpl shaft 33 is' provided with a second worm50,`and meshingwith opposite sides of the same, are worm gears 51 carried by the upper ends of vertical shafts 52. The lower ends of these shafts have loosely mounted thereon gear wheels 53 which can be connected to and disconnected from said shafts by clutches 54. The gears 53 are in mesh with an intermediate idler gear 55 that is in mesh with a curved rack 56 fixed' to the front depressed portion 16 of the rear truck section 13. With this construction, it will be evident that if one or the other of the gears 53 is clutched to its shaft, the carriage and support will be swung in one direction or the other, and may be thus adjusted. When 'both gears are unclutche'd from their shafts, the carriage is of course fixed with relation to the truck. v'lIhe main drivin shaft 33 is furthermore provided witha third.-wor1n 57 in mesh with aworm wheel 58 that is. fixed to a countershaft 59, and this countershaft can -vbe clutched to or unclutched from a pair o-f sprocket wheels 60 disposed at the sides of the truck. The clutches .for ythis-,purpose areV indicated at 61;I ,and like the other clutches, may be operated by any well known means, which havev not been illustrated to avoid complications of the drawings. The sprocket wheels 60 are engaged with sprocket chains, 62 that extend forwardly and pass amundE sprocketwheels carried by ;a shaft 64 on which is Inpuntedadriving pulley or drum 65..' 'f

Y Passin around thev drum 65, and conserivenl thereby, is an endless conveyer elt l66 that also passes around a tension vdrum 67 journaled in rear of the drum 6.5 around a'front end. drum 68vjouvrnaled on. the support 30 and around Ya rear end drinn 69' journaled von the rear ends of the frame membersi28 in rear ofthe standards f-This belgie disposed .-atpan inclination, as, clearly shown in .-I{`ig.-I 1, the .upper .stretch or flighty eonstitutingthe active or 4conveylng member. and being formed intotroughshape orf-transversely. concaved by suitably positioned Vsets .of l(rollers. Extending alongside the -up-per stretch of the belt are retaining walls 7,1thatpireferaby overlap theedges of.; said belt, as illustrated in Fig.

3, these walls extendingv from the rear em s of the 4support plates 30.

'The frontend. effthe support plates 30, as

illustrated more particularly in Figs. 10 and 11,- are formed into casing heads 72, and are provided with central openings 73 whichas illustrated in Fig. 5, receive theendslof a, fixed axle 74 that constitutes a cross stay for the front end 'ofthe support. The said head 72 furthermore has gudgeons or hubs 75 `surrounding theends of the aXle y74 and on these hubs are rotatably ournaled the heads 76 0fadrun, comprising said heads 76 and peripheral spaced wall sections 77 having inturned terminal flanges 78 bolted, as shown at 79 to the heads 76. The bearings for the heads 76 are preferably rollers 80, and these bearings are thus housed between the heads 76 and the head 72, suitable packin rings 81 and V82 being provided at the movale j o-ints. The heads 76 also have hub portions 83, to which are fixed sprocket wheels 84. Around these sprocket wheels pass sprocket chains 85A which, as shown in Fig. 1 also. pass around sprocket wheels 86 `fixed to the shaft .87 that carries the drum 68. Idlers 88 are preferably employed to take up the slack of the chains 85. The sprocket wheels 84 and the associated portions of l the sprocket chains, it will be noted, are also housed.

Carried by the drum 7 6*7 7 and operating in the spaces between the wall sections 77 are ore or earth receiving and carrying shovels 89, each 'being pivoted, as shown at 90, within the drum and having blade portions 91 movable into and out of said drums, the blade portions .and shanks 92 producing pockets 93. The projection of the shovels during the rotationof the druin is effected by cam members I94 fixed tothe axle .74, and

thein retrocession is secured by -cam tracks 95. fixed to the inner sides ofthe. support plates 30, as shownin F ig.l 11. The rearlill or feeding apron 98 comprising a-rear'wai-div and downwardly inclined plate pivoted at its, lowerendpas shown at 99, 'to links 100 that are pivot'allyinounted as shoivn at-101 inl Fig. ,11n 'llhcqplate isV proided with a dependingfinger 102 Xedthereto, and this finger is en aged by cam teeth 103 carriedby .In orderto. adjilst the support, and .con-

' sequently the idigging and elevating member withrespect tothe truck any suitable means may -be employed. For example, there is illustrated in Figs. 11 and 12 a double ended .Tight .and left hand screw. 104 l having a 5vcentral turning head 105, the upper. end of the screw being threaded into a nut 106 that is pivotally mounted as shown at 107 upon the plate 30. The lower end of the screw in like manner has a threaded engagement with a nut 108 journaled as shown at 109 on the carriage. It will be understood that one of these screw connections is employed for each support plate 30.

The carriage, as will be evident by reference toFig. 2 is capable ci a very consider'- able lateral swinging movement beyond the sides of the truck, and in order to properly support the said carriage when moved be- 50. vated, carrying the material upwardly over j same. 60...

yond the truck, the following mechanism is preferably utilized. Swinging arms 110 are pivoted at 111 to the sides of the truck, and their free ends have upstanding pintles 112. These pntles are slidable in flanged guides L13 fixed, as shown at 114 to the opposite sides of the carriage. The rear ends of the guides are open, as indicated at 115. With this `construction when the carriage swings beyond one side, it will be evident as indicated in Fig. 7 that the arm 110 on one side will swing outwardly and act as a supplemental support to the carriage, while the arm on the opposite side will remain in its folded position against the truck as the guide will disengage therefrom since the pintle will pass through the open portion 115.

Briefly described, the operation of the apparatus is as follows. The truck with the mechanism thereon is advanced to the pile ofore or other material by suitably operatingr the driving wheels 19', and in this oonnection, attention may called to the fact that thearticulated construction of the truck permits the same t0 operate in confined places and make short turns. When positioned, the driving l'nechanism for the shoveling and elevating means is thrown into operation. ltwill be understood that the shoveling .drum is rotated so that its lower portion moves forwardly and its vvadvance portion moves upwardly. Consequently, as "illustrated in; Fig. 6, the shovels will be successively projectedv from the drum into the material, and at the same time will be ele.-

the drum and depositingit upon the feeding apron. This apron is continuously oscilf lated so` as; to spread the material and prevent lodging of lumps and the like, thereby effecting its delivery upon the receiving end ofthe conveyer belt. The belt inl turn trans .ports it upwardly and rearwardly over the carriage and as indicated in Fig. 1` deposits .itin-a suitable vehicle placed in rear of the The. mechanism of course can be readily swung from side `:to side so that it i has a wide range of action, and permitting :itsv use under substantially all -conditions that prevail.

' Erom the foregoing, it is thought that the .constuction. operation. and4 many advanbe apparent to those skilled in the art, without. further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to Without dcparting from the spirit or sacrificing any of the advantages of the invention.
